OBJECTIVE: This study demonstrated statistical correlations between a novel self-administered odor questionnaire (SAOQ) and other olfaction tests in patients with olfactory disorders, and the usefulness of this questionnaire was discussed. MATERIALS AND METHODS: Between December 2004 and November 2009 (5 years), the SAOQ was completed by 405 healthy people without any nasal diseases (Group A) and 539 patients with an olfactory disorder (Group B) at the Department of Otolaryngology, Hyogo College of Medicine. This was a prospective study. The SAOQ proposed by the Japan Rhinology Society is a self-administered survey consisting of 20 smell-related items: "steamed rice, miso, seaweed, soy sauce, baked bread, butter, curry, garlic, orange, strawberry, green tea, coffee, chocolate, household gas, garbage, timber, stercus, sweat, flower, and perfume". The normal reference range of scores (%) of the SAOQ was calculated in Group A. To determine whether the results of the SAOQ were correlated with those of visual analogue scale (VAS) and T&T olfactometer, pre- and post-treatment results of the SAOQ and olfaction tests were analyzed. RESULTS: The questionnaire response rates were 99.5% (403/405 people) in Group A and 95.9% (517/539 patients) in Group B. The statistically normal reference level of the SAOQ was determined as more than 70%. In Group B, the mean pre-treatment SAOQ score (20.4%), VAS score (16.5%), and T&T recognition threshold (5.0) significantly improved to values of 46.7%, 41.1%, and 4.1 after treatments, respectively (n=249). Both pre- and post-treatment SAOQ scores (ΔQ) had statistically significant relationships with those of VAS and T&T (n=249). CONCLUSION: The utility of the SAOQ as an easy method of estimating olfaction was suggested. Copyright Â
